Lamotrigine-induced hemophagocytic lymphohistiocytosis with Takotsubo cardiomyopathy: a case report.

This case highlights that medication-induced hemophagocytic lymphohistiocytosis appears to respond similarly to the same dexamethasone and etoposide treatment regimen developed for other non-drug-induced forms of hemophagocytic lymphohistiocytosis. With the continued cessation of the offending agent there has not been need for maintenance therapy and no relapse to date. In addition, given the risk for cardiomyopathy, a clinical complication not classically associated with hemophagocytic lymphohistiocytosis, echocardiogram and telemetry monitoring should be considered in the initial workup of suspected hemophagocytic lymphohistiocytosis.
